FOUNTAIN PEN.

Application filed April 28, 1822, Serial No. 557,075. Renewed March 5, 1926.

This invention relates to fountain-pens and has for its object to provide a fountainpen with means whereby the ink passage through the feed is kept clean by means of a cleaning wire attached to the cap and passing through the pen point and the feed passage when the cap is in position to cover the pen point. By this invention the tendency of fountain-pens to clog owing to evaporation when not in use is eliminated by means of a cleaning wire which passes through the point into the groove when the cap is put on and prevents the storage of a large body of ink in the groove and in the nib, as well as having a tendency to prevent leakage in case the pen is inadvertently put in the pocket with the point down.

A preferred form of the invention is shown in the accompanying drawing wherein- Figure 1 is a section showing the cap in place,

Figure 2 a similar section showing the cap partly withdrawn,

Figure 3 a section showing the cap more nearly in closed position,

Figure 1 a view showing the cap on the rear end,

Figure 5 a section on the line 55 of Figure 1,

Figure 6 a section on line 66 of Figure 1,

Figure 7 a section on the line 7-7 of Fig ure 1, and

Figure 8 a plan view of the pen point, and

Figure 9 is a modification.

1 represents the barrel having the rear taper 2 to receive the cap, the screw thread 3 for receiving the cap and the front taper a for stopping the cap. 5 represents the cap having the taper 6 to cooperate with the tapers 2 and a and the screw thread 7 to en gagethe thread 8. The cap is also provided with centrally mounted cleaning wire 8 anchored in the end 9 thereof as by being upset and molded therein as shown in Figure 7, and wire 8 being of sufficient length to can tend up into the reservoir 10 when the pen is closed, as seen in Figure 1.

The front end of the barrel is provided with a guide shoulder 12 which has a sliding centering fit within the cap, the portion 13 of the barrel between threads 3 and shoulder 12 also preferably having a sliding fit. 1a is the feeder shown in section in Figure 1 having a feed groove 15 and 16 is the pen point fastened in the front end of the barrel by the nib let according to common practice as shown in Figure 5. The pen point is preferably inclined to the wire 8 as seen in Figure 1 and may have an oval shaped hole 17 of proper size to pass the wire 8 as in ordinary pens, but preferably is provided with a slight projection or conical hood 18 having afiaring opening acting as a guide to receive and pass the wire 8. The only change in presentpractice is that special dies would be made to form the pen point so as to have it inclined relatively to the wire 8 to permit the wire to pass through the hole 17, and the dies to also form the conical hood 18 if used.

In Figure 9, the funnel on the pen is omitted, but is transferred to the feeder as at 19, so that the point of the wire 8 will slightly spring the pen point and itself flex slightly in passing into and out of the groove 15. Between funnel 19 and groove 15 the nib fits the inner curvature of the pen point below hole 17 as is customary so that leakage from the groove will not occur.

The foregoing constructions have a number of practical advantages among which are that the wire automatically keeps the groove and nib clean, and also sufficiently fills the groove to prevent flow of ink therein so that the pen will not leak even if held downward, and also retards evaporation as it practically closes the hole in the pen point as well as the groove in the feeder. The iiivention is further of advantage in that it requires little or no modification in present practice but only a slight change in tools, as the wire can readily be centered and molded in the cap when it is formed.

l Vhilethe invention is shown herein inthe preferable form having a screw cap with the cleaning wire centrally mounted therein it is obvious that this is merely one form of cap guiding means for insuring that the point of the wire will pass through the hole in the pen point and that other constructions such as the ordinary frictional cap may be used with or without the guiding shoulder 12, but this guiding shoulder 12 is considered advantageous whether or not the cap be screwed or pushed on. Also other forms of guiding means than that specifically shown may be employed.

ltlodifications and changes may be made in the details herein disclosed without departing from the scope of the appended claims.

I make the following claims; I a

1. In a fountain-pen, a barrel, a pen point, a feeder having a feed groove covered b the pen point and mounted in the barre, and a cap having a wire adapted to pass into the feed groove when the cap closes the pen.

2. In a fountain-pen, abarrel, a pen point mounted therein, a feeder with afeed groove therein, a guiding means associated with said pen point and leading to the feed groove, and a cap having a wire adapted to pass into said guiding means and through the feed groove when the cap eloses the pen.

3. In a fountain-pen, a barrel, a pen point, a feeder providedavith a feed groove next to the, pen point mounted therein, a conical guide. in line with the feed groove, and a cap havinga Wire adapted to pass through the said guidetinto the feed groove when the cap closes the pen. 7 I

v4. In combination With a fountain-pen cap, of a pen point cleaning wire mounted therein.

5. Incombination with a fountain-pen cap, a cleaning Wire centrally mounted therein and adapted to pass between the pen point base and the feed groove when the pen is closed.

6. In combination with a fountain pen cap, a barrel having a guiding shoulder for centering the cap on the barrel, a Wire carried by the cap, a pen point, a feeder with a feed groove next to the pen point. and a passage for the wire fromthe exterior of the pen point into the feed groove when the cap and barrel are centeredand closed, 1 I

7. Aiountain pen comprising in combination a barrel, a pen point, a feed passage for said pen point, and a cap having a wire positioned to pass into said feed passage when said cap closes the pen. p H
